Polymer Taumaha Ngota Teitei o te Polyethylene Oxide (PEO) | Matrix Tukunga Tauwhiro mō ngā Papa Waikawa | E Tutuki ana ki te USP/EP/ChP

Ko tā mātou Polyethylene Oxide (PEO) he homopolymer kore-ionic teitei te taumaha ngota, wairewa-wai, e wātea ana i roto i te whānuitanga o ngā taumata matotoru (te taumaha ngota mai i te 100,000 ki te 7,000,000)He mea whakamahi whānuitia hei tāpiri mō ngā momo horopeta totoka ā-waha. Ko ngā whakamahinga matua ko: te hanga i te matrix tuku-tonu (te whakamakuku tere me te hanga i te kirikiri mō te tukunga rongoā 10+ hāora), he mea piri ki te kiri mō ngā pūnaha pupuri-waha me te puku, here mō te whakapūpū me te pēhi tika, me te kaihopu hanga kiriata mō ngā kiriata angiangi me ngā paninga taputapu hauora. E rite ana ki ngā rongoā USP-NF, EP, me ChP me te rēhitatanga CDE F20220000511.He tere te makuku, he kaha ki te pupuhi, he āhua kirihou wera, ā, he āhua kore-ionic (kore reka, kore tae)
